The strut-type hybrid system can be made in different geometric shapes, which are affected by: the number and arrangement of struts, the shape and position of the cable in relation to the girder, and the size and shape of the cross-section of the girder. When choosing a system, all the listed parameters can vary geometrically, which has consequences on the behaviour of the girder when carrying the load by directly affecting the change in the stiffness of the system. In addition to the geometric parameters, the stiffness of the hybrid system is affected by variations in the properties of the incorporated materials and their mutual relations. In this paper, based on a detailed parametric analysis, the principles of design, the choice of materialisation, and the possibility of further optimisation of the persistent-type hybrid systems are given, with the aim of additionally increasing the load capacity and reducing the deformability. The results of this research are presented in the form of general expressions and diagrams, which can be applied with sufficient accuracy in practice when choosing the form and materialisation of the hybrid system, as well as the possibility of further optimisation of the system by applying pre-stressing. Using the example of external pre-stressing of a glued laminated timber girder, with the assumption of ensuring the lateral stability of the system, the results of the analysis of the behaviour of such a system under load in real conditions, i.e. the influence of the environment and changes in material properties, are given.

Modern-day is defined as a period of globalization, a complex construct that can pose a threat to maintaining the uniqueness of a place and creating a distinctive city identity. The hypothesis of this paper is that, while the phenomenon of globalization is researched within different disciplines, a common interdisciplinary theme stands out - the experience and perception of urban space that further builds a unique impression of the observed scene. The assumption will be investigated through the formation of a qualitative model for examining the urban potential with the aim of affirming the visual quality of the place as an important factor in the construction of local identity. The established model is examined through case studies of the 20th-century heritage. This period was chosen because it represents the subject of a contemporary global discussion about the conservation, activation and use of heritage in urban structures. The premise is that the qualitative model can be adequately applied to architecture from this period and contribute to its visibility and understanding, as well as to the examination of its role in the creation of contemporary local identity. The research is significant because it enables an interdisciplinary consideration of heritage as a key factor in building the modern city identity based on its visual impression.

The discipline of preserving cultural monuments faces the challenge of large-scale contemporary and living heritage, which should be adequately documented and evaluated in order to be effectively protected and preserved. The valorization of architectural heritage, especially its most modern part, requires extensive consideration and estimation due to unstable social conditions, frequently changing purposes and temporal devastation. Many reasons can greatly affect our experience of the past as well as the conclusions, judgments and values we attribute to its monuments. This paper explores approaches to evaluating post-World War II architecture using the example of the Presidential Palace in New Belgrade. The research goal is to contribute to the objective valorization of the building based on different perceptions of the built structure and its surroundings through time, as well as specific meanings and emotions it causes for contemporaries.
